What I got for my 10 here can only be described as a joke, or at least what the price: As for money. Delivered is a thin fisselig Gürtchen of about 1 m length with a cheap-looking plastic push closure here. I suspect that the use of materials of this part is well below one euro. That the belt does the job and due to its length, if possible can also be used in cars where the child seat can not be fixed to the headrest may be.
But I think a price of about 2 to 3 would be for this Schrabbel still quite OK.
In any outdoor shop and here at Amazon, there are luggage straps and lashing straps in any lengths. These straps are extremely tear-resistant, made of equal more stable material, the closure far better produced (metal with serrated implementation) and all in all a lot more trustworthy than this scrap, which conjures a quality only by the "Cybex" lettering that simply are not given is.
I have seen at Amazon belts (2 pieces at 40 cm, which would have given me) for together 6,90.
The price of this product is not a moment for me to understand.
